Pro's and Con's of the OMS r-1 reg

[bburns24]

I have been thinking of transfering a OMS r-1 reg to my rig. I understand this is considered a deco reg. Why and what are the pro's and con's?

Pros:
-100% O2 clean
-venturi switch

Cons:
-no env. kit
-not available in yoke
-limited ports (1HP, 3LP)
-stupid colour for a primary.

I guess it depends on what you are using it for. Is it as a primary set-up or for doubles.
